An Ohio trucker accused of throwing chunks of iron ore through the windshields of cars says he did it because the drivers wouldn't lower their high beams.

According to The Associated Press, 41-year-old Glenn Rogers of Elyria, OH, pleaded guilty to throwing the chunks of ore at two cars and faces possible prison time.

Sheriff's officers told The AP more than 30 drivers reported broken windshields caused by chunks of ore on rural highways just east of Cleveland.
